Electronic circuit breaker ESS30-S
Economical and compact.
The electronic circuit breaker ESS30-S
with physical isolation is a “low energy
breaker” for DC 24 V applications. It
is approved to VDE EN/IEC 60934 and
UL1077 as a circuit breaker for equipment
protection and supplementary protector
and therefore ideally suitable for the use
in centralised and decentralised power
supply units. The compact, plug-in type
device was designed for mounting on
the power distribution modules 17plus
and 18plus as well as on the SVS power
distribution systems.
Benefits
● Saves energy costs through
1/3 lower power loss compared to
competitive solutions.
● Saves space by means of 30 % less
installation depth than equivalent
solutions.
● Enhances system availability by
means of a clear failure detection
and signalling.
